Abstract: This disclosure provides an encryption/decryption system, an optical module, and a related apparatus and system, and belongs to the field of network communications technologies. The encryption/decryption system includes an encryption/decryption component, a first interface component, and a second interface component. The encryption/decryption component is configured to encrypt a first physical layer data stream from the first interface component and transmit the encrypted first physical layer data stream to the second interface component, and is configured to decrypt a second physical layer data stream from the second interface component and transmit the decrypted second physical layer data stream to the first interface component. According to this disclosure, a delay caused by encryption/decryption during data transmission can be reduced.

Abstract: A receiving device determines that a first PHY needs to be added to a first FlexE group in a working state. The receiving device performs a deskew on the first PHY or each PHY in the first FlexE group based on a received data stream corresponding to the first PHY and a received data stream corresponding to each PHY in the first FlexE group, and restores a data stream corresponding to a client from a PHY in the first FlexE group. If a skew between the data stream corresponding to the first PHY and the data stream corresponding to each PHY in the first FlexE group after the deskew is performed is zero, the receiving device restores a data stream corresponding to a client from a PHY in a second FlexE group so that flexibility of adjusting a PHY in a FlexE group in a working state is improved.

Abstract: An embodiment provides a constant bit rate (CBR) service bitstream processing method. In that embodiment, the CBR service bitstream is received; a code block stream is obtained based on the service bitstream. An encoding type of the code block stream is M bit/N bit encoding, M is a positive integer, N is an integer not less than M, the code block stream includes a first-type code block and a second-type code block, the first-type code block includes M service bits, the second-type code block includes L service bits, and L is an integer less than M and not less than 0. The ode block stream is sent. A quantity of service bits carried in the second-type code block may be flexibly adjusted.

Abstract: A first communication apparatus obtains a first ciphertext data stream, and sends the first ciphertext data stream. The first ciphertext data stream includes a first alignment marker (AM) and an encrypted first data segment. At least one of some bits in a first AM lock information field in the first AM, some bits in a first lane identification information field in the first AM, or some or all bits in a first check information field in the first AM carry encryption parameter information of the first data segment.
